I have to question where your SM is if you are having challenges. There is a chain of command in Scouting. It is there to use and as a protection for its leaders both youth and adult. If a youth member cannot resolve behavior problems of youth members then its time for the Scoutmaster to step in and deal with the problem.
The first issue is program. If you are running a good program that interests the Scouts discipline problems will be limited. They will naturally want to pay attention. If your program is mediocre then that is your problem not discipline.
If you have "problem scouts" and I have certainly seen a few after too many years as a Scoutmaster you need to deal with them through the chain. First Patrol Leaders trying to deal with them, troop guides, ASPL finally SPL . If the scouts cannot resolve the problem then the adults need to step in.
A Scoutmaster's conference with the offender- If that does not work a Board of Review- If that doesn't work or if an offender is being totally out of control or a hazard to himself or others its time to send him home.
If there are constant problems from a scout a meeting with the Scoutmaster and Committee Chairmanm and the Scout and his parents is the next step. Perhaps even a probation period. If that does not work then finally expulsion from the Troop.
This last week we finally had to pull the plug on a scout who just wasn't getting the picture. The measure I used was this- His behavior had gotten to the point that it was having an adverse effect on other Scouts. He was affecting the program of the troop so negatively and so constantly that there was no longer any benefit of his presence.
This determination belongs with adults not scouts. I think I heard an audible sigh of relief from the Troop Leaders Council when we reached this decision.
